Abstract: Provided is a control stick capable of measuring rotation angles thereof and automatically returning to an original point after the rotational movements. The control stick includes a rotating rod rotated in a yawing direction and a pitching direction, a first spring which returns the rotating rod to an original point when the rotating rod rotates in the yawing direction, a first rotation angle measurement portion which measures a rotation angle of the rotating rod in the yawing direction and transmits the measured rotation angle to a controller of the motion simulator, a second spring which returns the rotating rod to an original point when the rotating rod rotates in the pitching direction, and a second rotation angle measurement portion which measures a rotation angle of the rotating rod in the pitching direction and transmits the measured rotation angle to the controller of the motion simulator.
